Re: [Orclib-users] OCILIB vs OCCI

[vincent r. <vin...@ya...>]

Hi Xavier,

You've pointered out the weakness of OCCI that explains why it has never
been a great Oracle success !
Another major issue with OCCI is that you've have to deal with object
pointers in C++  and is not the best C++ design and not STL like oriented.

OCILIB is compatible with all C compilers and all Oracle plaforms, in their
32/64 flavours.

Another thing is Version 4.0 of OCILIB introduces a new C++ API  : OCILIB++
: full C++ design, based on templates, using right design patterns.
No user dynamic object allocation (that is a pain for using exceptions with
effectiveness). Instead, the library uses stack objects that implements
internally references counting, raii, and so on.

OCILIB++ is a single C++ header (ocilib.hhpp) !
 It is already available on the SF.NET repository under the include folder.
It hasn't been released because i'm missing a bit of time for completing
the user documentation. You'll also find most of the c demo files under the
demo folder ported to their c++ counterparts :)

Give it a try !

It will be much easier to port OCCI code to OCILIB++ than porting to raw C
code !

Regards,


Vincent
